Combo box not dropping

[khariq]

When I display a combo box which I have loaded with strings (code below) the combo box doesn't "drop". I used the Ogre GUI demo as the basis for this. Has anyone ever run into this problem before?

Code: Select all

   CEGUI::Combobox* win = (CEGUI::Combobox*)CEGUI::WindowManager::getSingleton().getWindow("FleetDesigner/FleetDropDown");
   std::list<std::string> fleets = GameManager::GetSingleton().GetAvailableFleets();
   std::list<std::string>::iterator itr = fleets.begin();
   int i = 1;
   for (; itr != fleets.end(); itr++)
   {
      win->addItem(new CEGUI::ListboxTextItem((CEGUI::utf8*)(*itr).c_str(), i++));
      GameManager::GetSingleton().GetLog()->WriteMessage("Name added to drop down: " + (*itr));
   }

   win->addItem(new CEGUI::ListboxTextItem((CEGUI::utf8*)"Testing", 0));


XML Layout code

Code: Select all

<Window Type="TaharezLook/Combobox" Name="FleetDesigner/FleetDropDown">
         <Property Name="AbsoluteRect" Value="l:512.000000 t:14.000000 r:640.000000 b:38.000000" />
         <Property Name="RelativeRect" Value="l:0.800000 t:0.030000 r:1.000000 b:0.080000" />
         <Property Name="ClippedByParent" Value="false" />
               <Property Name="ReadOnly" Value="true" />
         </Window>

Hello,
The size of the combobox, is in fact the size of the dropdownList so i guess that your size is a little too small, perhaps.

I found the problem. I forgot to tell Ogre to pass the clicked event for this widget to CEGUI. However now I get a new problem. Does a combobox not support the EventMouseEnters and EventMouseLeaves events? Because these subscriptions are not firing.

Code: Select all

mEventSubscriptions.push_back(
      wMgr.getWindow("TestCombo")->subscribeEvent(
         CEGUI::Window::EventMouseEnters,
         CEGUI::Event::Subscriber(&MainMenuHandler::MouseOver, this)
         )
      );
   mEventSubscriptions.push_back(
      wMgr.getWindow("TestCombo")->subscribeEvent(
         CEGUI::Window::EventMouseLeaves,
         CEGUI::Event::Subscriber(&MainMenuHandler::MouseOff, this)
         )
      );

...

bool MainMenuHandler::MouseOff(const CEGUI::EventArgs& e)
{
   if (InputListener::GetSingletonPtr())
      InputListener::GetSingletonPtr()->MouseOverGUI(false);
   GameManager::GetSingleton().GetLog()->WriteMessage("Mouse moved off GUI");
   return true;
}

bool MainMenuHandler::MouseOver(const CEGUI::EventArgs& e)
{
   if (InputListener::GetSingletonPtr())
      InputListener::GetSingletonPtr()->MouseOverGUI(true);
   GameManager::GetSingleton().GetLog()->WriteMessage("Mouse moved over GUI");
   return true;
}

Could you post the code on how you fixed the drop down problem? My comboboxes aren't dropping down either. Thanks.

Hope this helps

   //setup any subscriptions

      );

}

bool SkirmishMenuHandler::OnFleetDropDown(const CEGUI::EventArgs& e)

   CEGUI::ComboDropList* list = (CEGUI::ComboDropList*)CEGUI::WindowManager::getSingleton().getWindow("FleetDesigner/FleetDropDown/DropDownList");
   
   list->show();
   
   return true;
}


if not post what you've got and I'll take a look.

I've encountered the same problem whereas my Scrollbar will not fire off for the EventMouseEnters Event it is subscribed to.

Has anybody figured out how to fix this?

thanks,
dave
